For example, the case where the three-side seal packaging body ZA2 (see FIG. 6D) is manufactured by a three-side seal packaging machine is mentioned.

  Next, the manufacturing process of the three-sided sealed package ZA2 will be described with reference to FIG. FIG. 6 is a schematic view showing a manufacturing process of the three-way seal package ZA2. FIG. 6A shows a state in which the film YA3 is folded in half so as to sandwich the article XA1 and overlapped with each other. FIG. 6B shows a state in which the frame seal sh2 is applied to the region around the article XA1. FIG. 6C shows a state in which the paper is cut horizontally. FIG. 6 (D) shows a state in which the three-way seal package ZA2 is cut vertically. Although the films YA3 folded in half and overlapped with each other have their edges aligned, they are illustrated with their edges shifted for convenience of expression.

  The films YA3 are folded back in half along the longitudinal direction and overlapped with each other so as to sandwich the article XA1 supplied from the article supply apparatus (not shown) (see FIG. 6A).

  Then, the film YA3 superposed on each other so as to sandwich the article XA1 is heated while the area around the article XA1 is sandwiched between a pair of upper and lower frame sealers (not shown), whereby the frame seal sh2 is placed in the area. Is performed (see FIG. 6B).

  Then, the film YA3 with the frame seal sh2 is cut in the width direction so that the edges along the longitudinal direction are not cut by a pair of upper and lower die roll cutters (not shown). Thereby, the cutting line cv1 and the cut line cv2 are formed in the film YA3 (see FIG. 6C).

  Thereafter, the film YA3 on which the cutting line cv1 and the cut line cv2 are formed is a pair of upper and lower cutting blades (not shown), and the edges along the longitudinal direction are cut in the longitudinal direction to become scrap SC2 (FIG. 6D). )reference). As a result, the part excluding the scrap SC2 becomes a three-sided seal package ZA2 (see FIG. 6D).

  The scrap SC2 is taken up and collected by a take-up roll (not shown).

  Or in the said embodiment, although frame seal sh1, sh2 is performed with respect to film YA1, YA2, YA3, this invention is not limited to this, A vertical seal and a horizontal seal are applied with respect to film YA1, YA2, YA3. And may be performed separately. That is, in the above embodiment, instead of the frame seal, the horizontal and vertical seals may be performed in separate steps.

  Next, another manufacturing process of the four-side sealed package ZA1 will be described with reference to FIG. FIG. 7 is a flowchart showing another process for manufacturing the four-side sealed package ZA1 with a four-side sealed packaging machine (not shown). Here, only the characteristic portion will be described, and description of the same configuration as the step shown in FIG. 4 will be omitted as appropriate. In addition, only the characteristic part will be described in the processes described below.

  As shown in FIG. 7, after the supply step S200 and the sealing step S210, in the horizontal cut step S220, the films YA1 and YA2 subjected to the frame seal sh1 are end portions along the longitudinal direction by the horizontal cut means (not shown). The inner region of the films YA1 and YA2 is cut in the width direction, leaving an edge. Thereby, the cutting line cu1 is formed in the films YA1 and YA2.

  Then, in the cut line forming step S230, the films YA1 and YA2 on which the cutting line cu1 is formed are cut in the cut line forming means (not shown) in the longitudinal direction of the film YA1 and YA2 at the end of the cutting line cu1 or the end part. A cut cu2 having at least a spread in the longitudinal direction of the films YA1 and YA2 is formed on the edge side along the line.

  Then, the part excluding the pair of scraps SC1 becomes the four-side sealed package ZA1 through the vertical cutting step S240.

  Next, still another manufacturing process of the four-side sealed package ZA1 will be described with reference to FIG. FIG. 8 is a flowchart showing still another process for manufacturing the four-side sealed package ZA1 with a four-side sealed packaging machine (not shown).

  As shown in FIG. 8, after the supplying step S300 and the sealing step S310 and before the horizontal cutting step S330, the film YA1 and YA2 having the frame seal sh1 in the cut forming step S320 are cut by a cut forming means (illustrated). (Omitted), and a cut cu2 having at least a spread in the longitudinal direction of the films YA1 and YA2 is formed on the end portion of the cutting line cu1 or the edge of the portion along the longitudinal direction of the films YA1 and YA2. It is formed.

  Then, in the lateral cutting step S330, the films YA1 and YA2 in which the cut cu2 is formed are laterally cut (not shown), and the inner regions of the films YA1 and YA2 are wide except for the edges along the longitudinal direction. Cut in the direction. Thereby, the cutting line cu1 is formed in the films YA1 and YA2.

  Then, the part excluding the pair of scraps SC1 becomes the four-side sealed package ZA1 through the vertical cutting step S340.

  As shown in FIGS. 7 and 8, linear cuts cu2, cu3, cu4 (FIGS. 5A, 5B, and 5C) are formed in a cut forming process different from the horizontal cutting process. ))), The cuts cu2, cu3, cu4 may be formed between both ends of the cutting line cu1, so the cuts cu10, cu11, cu12 (FIG. 5 (I), FIG. 5 (J) ) And FIG. 5 (K)) are preferably formed apart from the cutting line cu1.

  Alternatively, the present invention may be a continuous packaging machine in which the embodiment is modified and the frame sealing device 11 is moved in the flow direction to perform sealing.

  Alternatively, in the above embodiment, the pair of upper and lower continuous feed belts 13a and 13b may be a pair of upper and lower intermittent feed belts that run intermittently.

  Alternatively, the lateral cutting means of the present invention may be a rotary cutter or a reciprocating cutter device. The rotary cutter or the cutter blade of the reciprocating cutter device may have a detachable structure. Since the vertical cutting means is configured to be capable of adjusting the position in the width direction, various sizes of packaging bodies can be combined and packaged with a single packaging machine.
